EXCLUSIVE: A taxpayer-funded Pentagon consultant who developed armor, ballistics, shaped-charge and explosives software went to China—and taught researchers from its state weapons complex how to penetrate armor.

In the audience: personnel from China’s state arms industry—including the institute responsible for Chinese tank and armored-vehicle research. American taxpayers funded the expertise. China’s weapons industry got the lesson. RECEIPTS: bit.edu.cn/xww/xzw/xsjl1/a10… bit.edu.cn/tzgg17/jzyg2/a102…
